Leviticus 23:29-39

²⁹For whatsoever soul it be that shall not be afflicted in that same day, he shall be cut off from his people.

³⁰And whatsoever soul it be that doeth any manner of work in that same day, that soul will I destroy from among his people.

³¹Ye shall do no manner of work; it is a statute for ever throughout your generations in all your dwellings.

³²It shall be unto you a sabbath of solemn rest, and ye shall afflict your souls; in the ninth day of the month at even, from even unto even, shall ye keep your sabbath.

³³And the LORD spoke unto Moses, saying:

³⁴Speak unto the children of Israel, saying: On the fifteenth day of this seventh month is the feast of tabernacles for seven days unto the LORD.

³⁵On the first day shall be a holy convocation; ye shall do no manner of servile work.

³⁶Seven days ye shall bring an offering made by fire unto the LORD; on the eighth day shall be a holy convocation unto you; and ye shall bring an offering made by fire unto the LORD; it is a day of solemn assembly; ye shall do no manner of servile work.

³⁷These are the appointed seasons of the LORD, which ye shall proclaim to be holy convocations, to bring an offering made by fire unto the LORD, a burnt-offering, and a meal-offering, a sacrifice, and drink-offerings, each on its own day;

³⁸beside the sabbaths of the LORD, and beside your gifts, and beside all your vows, and beside all your freewill-offerings, which ye give unto the LORD.

³⁹Howbeit on the fifteenth day of the seventh month, when ye have gathered in the fruits of the land, ye shall keep the feast of the LORD seven days; on the first day shall be a solemn rest, and on the eighth day shall be a solemn rest.
